Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier. Best free agentic option in VS Code. Use with Claude for best results.
